FIELD OF THE INVENTION

The present invention is placed in the field of accessories for firearms. In particular, the object of the present invention is a device for loading cartridges into a magazine of a firearm.

As is known, a magazine of a firearm consists of a chamber open at the top and closed below by a bottom. Inside the chamber a thrust mechanism is provided, usually consisting of a follower and a spring which, resting on the bottom, pushes the follower upwards.

The cartridges are loaded manually, inserting the cartridges from the top into the chamber and using one's thumb to push them against the resistance provided by the thrust mechanism.

The loading operation becomes more and more difficult as the chamber fills up, as the resistance action exerted by the spring increases. So much so that, if several magazines are to be loaded, the operation becomes extremely tiring and difficult if one lacks the necessary strength.

STATE OF THE ART

Loading devices designed to facilitate the loading of cartridges into the magazines are known.

However, such devices have some drawbacks, such as, for example: the functional and structural complexity, especially for the models intended for professional use, with consequently significant costs for the end user; the need to intervene also with one's hand to position the cartridge correctly; the lack of effectiveness in reducing the resistance of the spring; the necessity to provide different models of devices according to the model and the caliber of the magazine.

SCOPE OF THE INVENTION

The object of the present invention is to construct a device for loading cartridges into a firearm magazine which satisfies the requirements of the sector and at the same time overcomes the drawbacks mentioned above.

This object is achieved by a loading device comprising:

• • a main body consisting of a casing having an inner compartment, comprising a left side, a right side, a rear shoulder and a front shoulder, which together laterally delimit the compartment;
  • an insertion opening at a lower end of the main body;
  • a main opening lateral to the main body; and
  • an action element projecting inside the main body from an upper end, opposite the lower end;
    wherein the width of the compartment between the rear shoulder and the front shoulder is such as to allow a rotation when the upper portion of the magazine is housed in the compartment.

DETAILED DESCRIPTION OF THE INVENTION

With reference to the enclosed figures, a device for loading cartridges in a magazine for a firearm is indicated collectively at 1.

According to one embodiment of the invention, the loading device 1 comprises an internally hollow body 2, having an inner compartment 4 suitable to house an upper section of a magazine.

The main body 2, preferably made of plastic material, for example in one piece by injection molding, consists of a casing having a thin wall, externally shaped in an ergonomic manner to facilitate gripping with one hand, wider towards the bottom and narrower, almost pointed, at the top.

For this purpose, the main body 2 has on one side a left side 6 having a convex outer surface 6a to follow the typical curvature of the palm of a hand holding the body 2, wider towards the bottom and narrower towards the top; similarly, on the other side, the main body 2 has a right side 8 having an outer surface 8a, which is also convex.

Between the two sides 6,8, the body 2 has a rear shoulder 10, which joins the two sides at the rear for the whole extension, from the base to the top, and a front shoulder 12, which joins the two sides 6, 8 at the front, but only part way.

In this way, in the front, between the two sides 6, 8, there is a main opening 14 for inserting cartridges.

The loading device 1 is also open at the bottom, where it has an insertion opening 16 for the upper portion of the magazine, which is, for example, rectangular.

Internally, the main body 2 has an action element or shank 20, projecting from the top of the casing for a predefined length.

The shank 20 extends from an upper end 22, connected to the wall of the casing, and an opposite free end 24 which, preferably, has an arched free surface 26.

With reference to FIG. 3, the loading device 1 is suitable to house therein the upper end portion of a magazine 30, usually consisting of a chamber 32 open at the top through a chamber opening 33 for loading cartridges, even of different gauges M1-M4, and closed at the bottom by a cover 34.

The chamber 32, generally with a rectangular prismatic shape, has a front face 32a, a rear face 32b and side faces 32c.

The magazine 30 further comprises a thrust mechanism consisting of a follower 38 and a spring, which, resting on the cover 34, pushes the follower towards the chamber opening 33.

On the top, the chamber 32 has two lips 36, 37, which partially delimit the chamber opening 33, converging with each other, so as to be able to hold a cartridge against the thrust of the follower 38.

In a first stage of a loading method (FIGS. 4a to 4c), the chamber 32 is inserted into the main body 2 of the loading device 1, and the main body 2 is arranged in a front abutment position in which it is rotated in front with respect to an imaginary chamber axis; in particular, in the front abutment position, the front face 32a of the chamber 32 abuts the inner surface of the front shoulder 12 of the main body 2.

When the magazine 30 is in place and the device 1 is gripped, for example with the right hand, a lowering action A is carried out, pushing against the thrust mechanism.

In this way, the shank 20 operates on the follower 38 and lowers it, against the action of the spring.

Furthermore, from the front abutment position, a rotation B or retroversion is carried out, bringing the device 1 into the rear abutment position (FIGS. 5a to 5c).

In the rear abutment position, the rear face 32b of the chamber 32 abuts against the inner surface of the rear shoulder 10 of the main body 2.

Maintaining the lowering action A, it is possible to introduce the cartridge M1 through the main opening 14 of the main body 2, inserting it into the chamber opening 33, between the follower 38 and the lips 36, 37 of the chamber 32; the cartridge M1 penetrates into the chamber opening 33, until it abuts against the shank 20 of the device 1, which keeps the follower 38 lowered.

Once the device 1 is released, the follower 38 pushes the cartridge M1 against the lips 36, 37, where it remains lodged (FIGS. 6a to 6c).

By means of an anteversion or rotation C of the device 1, the main body moves back into the front abutment position, in which the front face 32a abuts the inner surface of the front shoulder 12 of the main body 2 (FIGS. 7a to 7c).

In the front abutment position, resting the shank 20 on the cartridge M1 lodged between the follower 38 and the lips 36, 37 so that the shank is on top of said cartridge, a retroversion or rotation D is carried out, at the same time pushing down again by means of a lowering action E (FIGS. 8a to 8c).

The cartridge M1, under the action of the shank 20, which preferably operates mainly by friction on the cartridge M1, moves into the final position inside the chamber 32.

By maintaining the lowering action, it is possible to insert a new cartridge M1, and thus in succession until the magazine 30 is completely loaded.

According to a further embodiment of the invention, the device 1 comprises the main body 2 and coupled guides 42, 44, in the form, for example, of flat walls facing each other, inside the compartment 4, adjacent to the insertion opening 16, flanked by the sides 6, 8 (FIGS. 9a, 9b and FIGS. 10a to 10d).

The guides 42, 44 are made so as to leave a space 46 therebetween suitable for the guided passage of the upper portion of the magazine 30. The side faces 32c of the chamber 32 slide against the guides 42, 44.

Preferably, the loading device 1 comprises an adapter 50a-50d, applicable to the main body 2, preferably snap-fitted, so as to accommodate the tabs 42, 44 in the compartment 4.

For example, the adapter 50a-50d comprises a base 54, comprising an annular wall 56 which delimits the insertion opening 16. The guides 42, 44 protrude from the base 54, flush with the insertion opening 16.

The adapter 50a-50d further comprises, preferably, a pair of flexible tabs 58, 60, for example projecting from the base 54, each flanked with the respective guide 42, 44.

Preferably, the adapter 50a-50d is made in a single piece, for example of plastic material, obtained by injection molding.

The main body 2 also has through-windows 62, 64, each arranged on the respective side 6, 8; the windows 62, 64 are suitable to snap-engage the tabs 58, 60.

The adapter 50a-50d may snap-engage to the bottom of the main body 2, so that the tabs 58, 60 snap-engage in the respective windows 62, 64, and the guides 42, 44 are located inside the compartment 4, along the sides 6, 8.

Each adapter 50a, 50b, 50c, 50d, by virtue of the distance between the guides 42, 44, is suitable to guide laterally a predefined magazine or a predefined group of magazines.

For one of said adapters 50d, the inner perimeter of the annular wall 56 acts as a guide for larger magazines.

A loading kit comprises, for example, a main body 2 and a plurality of adapters 50a-50d, so that a user may modify the loading device and use it with multiple magazines.

Innovatively, the loading device described above satisfies the requirements of the sector and overcomes the drawbacks referred to with reference to the prior art.

In effect, due to the ergonomic handle, the lowering action of the follower is less uncomfortable, while the rotation movement allows the cartridge to be positioned correctly, without intervening directly with the other hand.

Moreover, advantageously, the loading device, provided with a set of adapters, may be used for several magazines. At the same time, the operations of disassembling an adapter and applying another adapter are very simple and fast.
